Navigating the Landscape of Solid Waste Management: Innovating Developmental Strategies for a Sustainable Environment

Effective solid waste management is decisive for environmental sustainability and community healthiness. This study addresses critical research gaps in scalable solid waste management (SWM) for developing economies through a systematic analysis of circular economy innovations, policy frameworks, and socio-economic barriers. Employing a dual-method approach combining a literature review and policy analysis, we identify infrastructure deficits, environmental justice trade-offs in waste-to-energy adoption, and formalization challenges for informal waste sectors as key constraints. Findings demonstrate modular technologies can reduce collection costs by 35%, while gamified education increases waste segregation by 60% in low-resource settings. The research proposes a justice-centered framework integrating three pillars: (1) Technical (low-cost modular solutions), (2) Social (formalized waste picker inclusion), and (3) Policy (equity-focused EPR reforms). By quantifying implementation metrics across 12 case studies, this work presents actionable pathways for building resilient SWM systems that balance ecological integrity, economic viability, and social equity.
